第一种方法：
NSURL *instagramURL = [NSURL URLWithString:@"instagram://location?id=1"];

BOOL hasInstagram = [[UIApplication sharedApplication] canOpenURL:instagramURL];

第二种方法：

// .h

@interface UIDevice (ProcessesAdditions)

- (NSArray *)runningProcesses;

@end

// .m

#import <sys/sysctl.h>

@implementation UIDevice(ProcessesAdditions)

- (NSArray *)runningProcesses {

intmib[4] = {CTL_KERN, KERN_PROC, KERN_PROC_ALL, 0};

size_tmiblen = 4;

size_tsize;

intst = sysctl(mib, miblen, NULL, &size, NULL, 0);

structkinfo_proc * process = NULL;

structkinfo_proc * newprocess = NULL;

do {

size += size / 10;

newprocess = realloc(process, size);

if (!newprocess){

if (process){

free(process);

}

return nil;

}

process = newprocess;

st = sysctl(mib, miblen, process, &size, NULL, 0);

}while (st == -1 && errno == ENOMEM);

if(st == 0){

if(size % sizeof(struct kinfo_proc) == 0){

intnprocess = size / sizeof(struct kinfo_proc);

if(nprocess){

NSMutableArray* array = [[NSMutableArray alloc] init];

for(int i = nprocess - 1; i >= 0; i--){

NSString* processID = [[NSString alloc] initWithFormat:@"%d", process[i].kp_proc.p_pid];

NSString* processName = [[NSString alloc] initWithFormat:@"%s",process[i].kp_proc.p_comm];

NSDictionary* dict = [[NSDictionary alloc] initWithObjects:[NSArrayarrayWithObjects:processID, processName, nil]

forKeys:[NSArrayarrayWithObjects:@"ProcessID", @"ProcessName", nil]];

[processIDrelease];

[processNamerelease];

[arrayaddObject:dict];

[dictrelease];

}

free(process);

return[array autorelease];

}

returnnil;

}

@end

// Example usage.

NSArray * processes = [[UIDevicecurrentDevice] runningProcesses];

for (NSDictionary * dict in processes){

NSLog(@"%@- %@", [dict objectForKey:@"ProcessID"], [dictobjectForKey:@"ProcessName"]);

}
